任务间自动触发与数据流--功能请求

What feature would you like to be added or updated?

场景：我用两个任务分别做"执行"和"审核"，目前需要手动复制消息。

希望支持：

任务完成后自动触发另一个任务 任务之间通过文件或 MCP 自动传递上下文 上下文达到阈值时自动新建任务并注入压缩后的 Handoff 提供任务编排 API（创建任务、发送消息、读取回复） 参考：Claude Code 的 Context Rotation、VNX Orchestration System

Why do you need this feature?

主要解决的痛难点有： 1.多任务并行但是独立； 2.任务文件不能共享 3.超长任务执行上下文坍缩 4.多任务间交互，采用不同模型执行任务，多任务交互进行 例如我的场景，我前期已经做了方案，现在执行中需要决策任务和执行任务交互，任务大，希望多个AI协作并有序执行。

Additional information that you believe is relevant to this feature request

Additional context:

My current workflow uses two separate Trae tasks/agents:

1. Executor agent:

   • Implements code changes
   • Runs commands/tests
   • Produces execution results and handoff notes

2. Reviewer/decision agent:

   • Reviews the executor's output
   • Decides the next step
   • Sends instructions back to the executor

Currently, I have to manually copy messages between these two task windows. This becomes inefficient and error-prone, especially for long-running tasks.

A practical implementation does not necessarily need full UI automation. Any of the following would be helpful:

• A task/session API to create a task, send a message, read the latest reply, and close/archive a task
• A project-level handoff file mechanism, for example .ai/handoff.md
• A way to automatically start a new task when context becomes too long
• A way to pass summarized context from one task to another
• MCP-based task orchestration support
• Hooks/events such as onTaskComplete, onContextThresholdReached, onMessageGenerated

Related examples or inspiration:

• Claude Code context rotation / handoff workflows
• VNX Orchestration System
• Multi-agent workflows where one agent executes and another agent reviews or plans

Expected result:

Trae users should be able to build a semi-automated or fully automated multi-agent workflow without relying on fragile GUI automation, copy-paste scripts, or manual window switching.
